That just means that the client has stat()'ed a file twice within the timeout specified by the vfs.nfs.access_cache_timeout sysctl, and has pulled the value from its cache instead of querying the server. > Version 2: (185583924 calls) > null getattr setattr root lookup > 0 0% 175265837 94% 66975 0% 0 0% 6407008 3% So here, 94% of the getattr calls were pulled from cache. --=20 Dan Nelson dnelson@allantgroup.com _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" Dan, Sorry, you were right I did mean getattr. Just curious, does this mean that 94% of the NFS calls made, where getattr() calls (175265837/185583924 =3D .944)? Thanks, Brian
